IMPROVEMENT IN SYRINGES.

Specification forming part of Letters Patent No. 199,479, dated January22, 1878; application filed 1 August 17, 1877.

To all whom it may concern:

Be it known that I, BENJAMIN F. SUTTON, of the city of Brooklyn, countyof Kings, State of New York, have invented certain new and usefulImprovements in. Enema- Syringes; and I do hereby declare the followingto be a full, clear, and exact description thereof, such as will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention consists of an improvement in that class of enema-syringeshaving an elastic bulb or air-chamber attached to a rigid suction orinlet pipe, and a flexible discharge-pipe.

A common method of construction is to attach the elastic bulbperpendicular to, or on an axial line with, the rigid inflexible inletsuction-pipe, while the elastic discharge-pipe leads from the rigidinlet-pipe at an acute right angle, thereby offering considerable obstruction to the flow of liquid from the elastic bulb, and requiring agreat exertion to compress the bulb and force the liquid out through thedischarge-pipe, thus tiring the hand of an invalid, while the positionof an elastic bulb, when attached to the rigid suction-pipe, asheretofore mentioned,is extremely awkward to hold perpendicular when thepatient is in a stooping position while using the syringe in a vesselplaced upon the floor, as is customary.

I am aware that in some syringes the elastic bulb and the injection-tubeare in line; but in all such cases of which I have any knowledge thebulb is at some distance from the suction-tube-a mo do of constructionwhich allows the suction-pipe to dangle about in the injecting fluid,greatly to the discomfort and inconvenience of the operator.

To obviate these faults I construct my improved syringe with the-elasticbulb attached to the side of, or at a right angle to, the rigidinlet-pipe, and on a direct or nearly direct axial line with theflexible discharge-pipe. This not only gives the operator entire controlof the suction-pipe, but the latter, being inflexible, affords a restfor the hand, and, as such, is a convenience and comfort to the invalid.

In the annexed drawing, making part of this specification, Figure l is aperspective view, showing my method of attaching the elastic bulb B tothe rigid inlet-tube A, and on an axial line with the flexibledischargepipe C. Fig. 2 is a sectional view of the same.

As instances may occur when it would be more convenient to attach thebulb perpen dicular to the rigid suction-pipe, Imake an opening at thetop P for this purpose. Thus the bulb may be either used at right angleto the rigid suction-pipe attached at R or perpendicular at P, theopening not closed by the bulb being closed by the cork Having thusdescribed my invention, what I claim is 1. The rigid inflexiblesuction-tube, having two. openings for attaching an elastic bulb eitherperpendicular with or at a right angle to said tube, in'the-mannerspecified, and substantially as set forth.

2. A syringe having a rigid suction-tube, with the elastic bulbconnected directly thereto at, or nearly at, a right angle, andaflexible discharge-pipe in the same axial line, substantially asdescribed.
